Well, when I look at http://openid.net/get-an-openid/ http://openid.net/get-an-openid/ I see Google, Yahoo, Livejornal, Hayes, Blogger, Flikr, Orange, Mixi, MySpace, Wordpress, AOL... There are six 'simple' providers listed. Spot checking: One of them has broken SSL (https://www.myopenid.com/signup https://www.myopenid.com/signup sources https://api-secure.recaptcha.net https://api-secure.recaptcha.net which has an invalid certificate). One of them looks completely broken for new accounts: http://claimid.com/register http://claimid.com/register "This account is hidden or does not exist." And of course there's this: http://www.untrusted.ca/cache/openid.html http://www.untrusted.ca/cache/openid.html which describes various security and privacy problems with OpenID.
